Websocket JSR-356因码头9.4.1而失效

websocket

Websocket JSR-356因码头9.4.1而失效,websocket,embedded-jetty,jetty-9,jsr356,Websocket,Embedded Jetty,Jetty 9,Jsr356,我当前的web服务器是嵌入式Jetty 9.1.5。它可以与JSR-356一起很好地创建websocket。这些天，我正在尝试升级到Jetty 9.4.1。除了websocket，其他一切都很好。我的代码如下所示：嵌入式码头和Websocket libs： Jetty服务器、Webapp上下文、Websocket配置：升级Jetty时我错过了什么吗？提前感谢。从您的设置判断，您将得到 wss://localhost:8443/myContext/ws/communication/5/kb

Jetty服务器、Webapp上下文、Websocket配置：

升级Jetty时我错过了什么吗？

提前感谢。

从您的设置判断，您将得到

wss://localhost:8443/myContext/ws/communication/5/kbui/None

您的

contextPath

不是

/context

，实际上是设置中的

/myContext

您删除了转储上的Servlet映射部分（这是重要的部分。heh）

但是，试图从

WebAppClassloader

或WebApp的ServletContext外部手动添加

WSCommunication

端点（包含在

WebAppContext

中）可能也是一个问题

您有3种选择：

JSR356自动方式

为

WebAppContext

设置字节码扫描和注释发现，让启动程序发现并自动加载

WSCommunication

端点

将以下内容添加到您的

webContext

webContext.setAttribute（“org.eclipse.jetty.websocket.jsr356”，Boolean.TRUE）；
webContext.setConfigurations（新配置[]{
新建AnnotationConfiguration（），
新的WebXmlConfiguration（），
新的WebInfConfiguration（），
新的PlusConfiguration（），
新的MetaInfConfiguration（），
新的FragmentConfiguration（），
新的EnvConfiguration（）}）；

并将

jetty annotations

依赖项添加到项目中

JSR356手动方式

使用

javax.websocket.server.ServerApplicationConfig

报告

WSCommunication

可从webapp启动中添加

Servlet规范的手动方式

这是最简单的方法。创建一个

javax.servlet.ServletContextListener

，将

WSCommunication

端点添加到

ServerContainer

公共类MyContextListener实现ServletContextListener
{
@凌驾
公共无效上下文已销毁（ServletContextEvent sce）
{
}
@凌驾
public void contextInitialized（ServletContextEvent sce）
{
ServerContainer=（ServerContainer）sce.getServletContext（）
.getAttribute（ServerContainer.class.getName（））；
尝试
{
container.addEndpoint（WSCommunication.class）；
}
捕获（部署异常e）
{
抛出新的RuntimeException（“无法添加端点”，e）；
}
}
}

webContext初始化是什么样子的？转储服务器（启动后）并在问题中报告其树<代码>服务器.dumpStdErr（）我修改post以添加服务器、Webapp上下文代码。我发布转储，因为大小限制为30000个字符，我必须为一些内容（如jar文件、servlet映射）放置占位符。我使用命令Server.dumpSteer（）而不是Jetty.xml中的选项更新了转储，它记录了更多的websocket。我看到一行奇怪的代码+~org.eclipse.jetty.websocket.jsr356.server。ServerContainer@6fda53a8-停止。我尝试了#1方法，效果很好。非常感谢。关于之前的代码如何在9.1.5上工作，你的意思是我设置websocket错误，但9.1.5仍然接受，转到9.4.1 Jetty服务器比它拒绝的更严格。对吗？另一个问题，在现实中，我的服务器可能支持多个上下文，所有3种方法仍然适用于多个WebAppContext？我测试了#1，适用于多个上下文（每个上下文都有自己的WSCommunication websocket连接）。
